+ https://bugs.webkit.org/show_bug.cgi?id=81963 WebProcess can get stuck in GC during many low memory signals.
+ <rdar://problem/11094830> WebProcess appears to get stuck in its GC handler (81963).
+ Remove the call to garbage collect in low memory signal handler. Did some testing with hitting the low memory handler
+ during Membuster and we would get back at most 100k - 200k. That isn't enough to help the system, and in
+ that state the GC collection can take a substantial amount of time.
+
+ Reviewed by Geoff Garen.
+
+ Performance Change, no change in behavior.
